This is a great little portable charger for my Apple Watch. The key ring holder is a really nice and convenient design making the battery charger easy to carry when traveling here and there. I know that from owning many different types of battery chargers that dropping any of these types of things can get damaged and not function properly in a bad fall or drop so I bought a case for it too. The case is really meant for a car key fob, it’s a very small case that is used on a key ring and is supposed to hold the car key remote inside. I think the case is called a key fob protector case for keychain, I bought the case on Amazon and even though it is a key ring case meant for a car key remote I use it to put my portable battery for my watch inside it instead to protect it from accidental falls, drops or helps against accidentally hitting the power on / off button, and protects it against bad weather when I’m traveling. The battery fits inside perfectly and is protected so it would be a good investment to get a covering like this to protect any type of portable batteries in general and it can cost only 6 dollars or more depending on the types of case you want to buy, just check out the measurements first and the case also has a key ring design too.. Now about the rechargeable battery, it arrived in perfect condition and early. I’ve charged my Apple Watch 11 with it and it worked perfectly and still has remaining battery life for another charge. The small button on the side of the unit turns the unit on and off. When charging my watch the unit displays the amount of battery life the unit has left, after charging the watch with the unit don’t forget to double click the side button to turn off the unit or it will remain on, make sure the unit is off and you will know this because the display screen will also be off. Same thing for charging the unit with the wall charger, the unit will blink while charging when it reaches 100 percent it will say 100 percent then the screen display goes dark signaling charging complete, when this happens unplug the battery charger from the wall and when you do this the screen will wake up and the battery unit will also turn on ready to charge your watch so if you are not immediately going to charge your watch right away double click the side button to turn off the unit and the screen will go dark meaning the battery unit is now off. It’s important to read the small booklet that comes with the unit to know how best to maintain the longevity of this battery charger, how to use the unit and battery care, this small instruction booklet is a very short read and very easy to understand. I love my new portable battery charger for my Apple Watch and it has saved me many times when my Apple Watch was running low and I was away from home unable to get access to my regular charger. I like the feeling of security that I don’t have to worry about my Apple Watch dying of low battery when I’m running errands because I have my portable battery charger on my keychain for emergency power to charge my watch where ever I am. I do recommend getting a small protective case for it as I mentioned earlier, it’s not necessary you can definitely travel with it and be fine without a case but since I tend to drop things and travel in snow, rain and bad weather it’s best to keep any type of power sources like batteries out of harsh elements and a case has seemed to work well in protecting my emergency go to needs like my new portable battery charger. I highly recommend this charger, it’s a really nice design, easy to carry, lightweight and small. I’m hoping it will last a long time, so far it’s been great, if this changes I will keep you updated. As for now after multiple uses it has saved me from my watch dying numerous times and that is why I bought this battery unit , it keeps on working great and so far has been extremely reliable. I highly recommend it.

Charged up to 100% in about 2 hours, then charged my watch 3 times from 5% to full and still had a little power left to top me up a 4th time from 50% to 80% before I needed to charge it again. One charge up keeps my watch full all week. Much better than the awkward standard charger and I can set it anywhere and I love that it's portable. Will be great for trips! Cute color too, and has a strong ring attached to bring it with you. Did not notice any heat when charging either. Brings my watch back to full battery life in about 45 mins. Very useful and worth the small price.

Does what it is supposed to, multiple times in one charge. Good purchase!

I love this watch charger. I keep it in my purse so I can charge whenever I want. It holds a charge well and charges my watch quickly. It is compact and pink so I love it!

Works very well. Only thing is that the magnet is not that strong and the watch doesn’t stay on that well! The powerbank also turns off when the watch is disconnected. I had some problems charging

Amazing watch charger. I love it because it is very easy and if you forgot to put your watch on charge the day before this little charger is a life saver for you. I have a Apple Watch Ultra and it really did charged it fully for 2 times as advertised! It is reliable and I like that it has a mini screen so I can see how much power I still have left in my charger

I take this with me everywhere! I love how convenient it is and that I can easily take it anywhere. It holds a charge for a long time, and it actually charges my watch faster than I expected!

PURCHASED JAN 2024

OUT OF COMISSION APR 2026

So this little charger was great, until it wasn't. I travel a lot for work, like every 4-6 weeks for a week at a time. I keep my toiletries packed and my backpack full of every possible cable and battery bank for every device including docks, a mouse, and this little travel power bank for my iWatch. I used this on and off for the two years and it was a staple in my kit, especially for overnight international flights.

It was easy to use with my Series 9, quick to recharge, and a decently priced item compared to competitors on the market. I never had any compatibility issues or connectivity problems.

I even purchased one for my mom so she could have a charger on the go for her Series 8.

One day earlier this year (approx. April 2026) I was going through making sure everything was charged for an upcoming trip and I noticed a hairline crack through the magnetic dock for the watch. I didn't think anything of it, and charged the bank. When I went to pick it up, I noticed it was no longer flat on the back and was wobbling on the desk. Annoying! Then I look closer, the lithium ion battery had swollen and cracked the case, most notably across the magnetic dock. Knowing that overheating and thermal run away is an issue with a compromised lithium ion, I left it on my desk at home to dissipate the battery and after a few weeks recycled responsibility.

I understand not everything lasts forever, and batteries do break down over time, but the safety risk of repurchasing isn't worth it's weight in my cable kit and has been replaced with an Apple folding dock.

My mom's is still in good condition, but I do keep checking it for cracks and deformations when I remember.

Fast delivery, works like a charm and very handy.
